FORT MYERS, Fla. (AP) — Five Transportation Security Administration workers at a southwest Florida airport have been fired and another 38 suspended after an investigation found they failed to perform random screenings last year.

The 43 disciplined workers, a combination of front-line screeners and supervisors, represent about 15 percent of the roughly 280 TSA employees at Southwest Florida International Airport in Fort Myers.

The News-Press reported Monday that it's one of the largest disciplinary actions TSA has taken in the agency's 10-year history.

The TSA said that during a two-month period last year, as many as 400 passengers who underwent routine screening at the airport never got additional random checks.
